@CaseySJ But isn’t exporting as HEVC in QuickTime Player encoding? See screenshots.

@digumo I don’t have an iPad which is new enough to work with Sidecar, so I can’t try it out. But as far as I have heard Sidecar doesn’t work with any T2 SMBIOS, no matter if iGPU is enabled or disabled.
So you always have to decide: Sidecar or fully working DRM? On my machine DRM is only fully working with iMacPro1,1 SMBIOS. The shiki boot arguments in iMac19,1 don’t solve the DRM problem fully. Netflix playback in Safari only works with iMacPro1,1 SMBIOS for example – at least on my machine.

Exactly my situation! I do get DRM playback of Netflix within Chrome, but not Safari. All other DRM, Audible, iTunes, etc. seem to work fine with 19,1 with shiki values. I just have the issue with Safari and Netflix.

I may be foregoing the Sidecar/iPad Pro in favor of the better FCP performance.

If you want HEVC support with IGPU disabled, use iMacPro1,1 system definition.

The down side is that I don't know of anyone who has gotten sidecar to work on iMacPro1,1.

I have HEVC with iGPU disabled and Vega 64 and SMBIOS is iMAC19,1

@svandive Yes, of course, and that’s how it supposed to be. BUT it doesn’t work correctly in Final Cut Pro X and Compressor only (takes ages to export and puts it all on the CPU instead of the Vega 64). It works great in all other applications (such as VideoProc, Premiere Pro or QuickTime Player).

I'm not sure if this adds any value or not... but I'm now configured as iMac 19,1 in headless configuration. When I sweep back and forth through my FCP timeline, iStats Menu shows my RX 580's processor is pegged - no activity shows up in the "Intel UHD Graphics 630 (Mobile)" section. I guess I have the whatcha-ma-callit, SSDT?, thingie that renames the graphics card with an "AMD" preface. Is it possible the Vega cards aren't alphabetically listed first, like my SSDT-renamed AMD RX 580 is?

In my “reorganize” post I stated QuickTime playback as being okay. Rereading your original post, I see that you did mention QuickTime export so I’ll need to fix the reorganize post a second time.

This is actually the reason for the reorganize post — to make all these little distinctions very clear.

I'm still on 10.14.6 and I've never been able to get HEVC working with dGPU and 19,1. I doubt this is a Vega 64 vs VII issue (but then maybe it could be), but do you remember what you did to get the HEVC support or was it just always working?

Also, just a quick question, but I had to find this out for myself... Have you clicked that refresh button between opening/closing VideoProc? When playing with various configurations I found it wasn't automatic.

@CaseySJ how do I check for the name? I currently have my iGPU disabled, but are the ??? the result of not having a valid SSDT? I need to learn more about those. Is it because the one in the list is starting with Vega 20 and not AMD?

System Information --> PCI will state the name of your AMD GPUs. The SSDT can be removed at any time to see what happens when the alphabetical order is reversed (i.e., when "Intel UHD 630" comes before "Radeon RX 580").

The RX580 SSDT renames the device from Radeon RX 580 to AMD RX 580. Because "A" in AMD comes before "I" in Intel, the SSDT allows apps to prioritize the AMD RX 580. By removing the SSDT, the name goes back to Radeon RX 580 or maybe RX 580, where "R" comes after "I".

System Configuration:

• Catalina 10.15.1
• BIOS F8 with MSR 0xE2 unlocked
• Intel i9-9900K
• Corsair Vengenace LPX 2 x 16GB + 2 x 32GB 2666MHz DIMMs with XMP Profile 1
• Clover v5098 (press "A" at Clover Boot Menu to determine your Clover version)
• EmuVariableUefi and FwRuntimeServices both copied to CLOVER/drivers/UEFI folder
• Using VirtualSMC instead of FakeSMC
• SMBIOS iMac19,1
• iGPU enabled with headless platform ID 0x3E980003
• Lilu and WhateverGreen installed only in CLOVER/kexts/Other with Inject Kexts set to Detect.
• M2M (top M.2 slot) = WD SN750 Black PCIe NVMe 1TB (Windows 10)
• M2P (bottom M.2 slot) = WD SN750 Black PCIe NVMe 1TB (macOS)
• Sapphire Pulse OC RX 580 in PCIe Slot 1
• Aquantia 10G Gaming NIC in PCIe Slot 3
• Broadcom BCM4360CD + Adapter WiFi/BT card in top x1 PCIe slot
• Original Intel CNVi WiFi/BT module still installed; using NO-CNVW SSDT to disable.

Test Conditions:

• Turn off USB drive for CCC backup (wanted to test NVME only)
• slide=0 enabled in all cases
• Make new config.plist without shiki bootargs
• Boot macOS NVME drive
• dart=0 debug=0x100 keepsyms=1 slide=0 vsmchbkp=0 -disablegfxfirmware

Results:

• Test 1: Success
• Test 2: Success
• Test 2, Increase DVMT to 128MB/MAX: Success
• Test 2, Increase DVMT to 1024MB/MAX: Success
• Switch to OpenCore and mirror quirks (except DisableVariableWrite) with test 2: Fail
• Test 2, Switch back to Clover, set DVMT back to 64MB/128MB defaults: Success

Odd that I can boot with the port of OpenCore's quirks + iGPU but then switch back to OpenCore with the same quirks except DisableVariableWrite (their replacement of EmuVariableUefi).
